Howerton was born in Okinawa Prefecture on April 13, 1976, the son of American parents Janice and Glenn Franklin Howerton Jr. He has an older sister named Courtney. His father's job as a fighter pilot was the reason he was born in Japan, and it required the family to constantly move. Almost immediately after his birth, the family returned to the U.S. to live in Arizona and then New Mexico. When he was three years old, they relocated to England, where they lived in Felixstowe. Four years later, they again returned to the U.S. to live in Virginia. They then had a stint in South Korea, where they were based in Seoul. When he was 10 years old, they returned to the U.S. for a third time and settled in Montgomery, Alabama.
